Calponin 1 is a 34 kDa protein that is predominantly found in smooth muscle tissue. It is a high-affinity actin-binding protein, but also interacts with tropomyosin, and calmodulin to modulate muscle contraction. When bound to F-actin, it inhibits the activity of the actin-activated myosin ATPase. Calponin 1 is regulated by reversible phosphorylation involving PKC and CAMKII kinases, and type 2A phosphatases. In non-muscle cells, calponin 1 may play a role in cell migration, motility, and proliferation.
Other homologies: Rat (92% sequence homology) and Mouse (83% sequence homology).
